Network data transmission method and front-end processor

Abstract

The embodiment of the invention provides a network data transmission method and a front-end processor. The network data transmission method is applied to a data transmission network comprising a plurality of terminals and a plurality of front-end processors, wherein each terminal corresponds to a front-end processor. The network data transmission method comprises the following steps: a first front-end processor obtains the first network data sent by the corresponding first terminal, and the destination address of the first network data is the address of a second terminal; the first network data is encapsulated to obtain the first text data, wherein the destination address of the first next data is the address of the second front-end processor corresponding to the second terminal; and finally, the first text data is sent to the second front-end processor, so that the second front-end processor sends the first text data to the second terminal after performing corresponding processing. According to the technical scheme provided by the invention, the analysis performed by the first front-end processor is not required by the application layer protocol involved in the first network data,therefore, the processing logic complexity of the first front-end processor is simplified, the probability of the failure of the first front-end processor is reduced, and the stability of the data transmission network is improved.

Description

technical field [0001] The invention relates to the technical field of power system information communication, in particular to a network data transmission method and a front-end processor. Background technique [0002] The relevant regulations on the security protection of the power monitoring system require that the security protection of the power monitoring system should adhere to the principles of security partition, network dedicated, horizontal isolation, and vertical authentication to ensure the security of the power monitoring system and power dispatching data network. Therefore, if individual businesses or their functional modules (or subsystems) in the production control area (high-density network) of the power monitoring system need to use public communication networks, wireless communication networks, and networks in uncontrolled states When the equipment communicates with terminals in the low-density network, a secure access area should be set up, and the commu...
